Cushion-tire.

In cushion-tues having retaining-bands for f I To all whom it may concern:

Be it known that I, JOHN H.'TooLE, residf Jourv H. Toons, or cnica'oo, y 1Ln1Noisj ing at Chicago, in the county of Cook and State f of Illinois, have invented certain new and useful Improvements in Cushion-Tires. of which ythe followi securing the elastic body in the rim it has beretofore been common practice to embed Vin or extend\through the elastic body or cushion element metallic supports -for the, bands- In practiceitlhas been found difiicult to construct elastic "strips with the supports embedded.

therein, an( the cost of manufacture thereof was materia "n increased by the process necessarily ado eden such manufact-ureand on account of t '.ore necessary in accurately laying the sup1 oi \ts\in the compound or rub-I ber. In some instances the elastic body was formed of parts separately formed and vulcanized together withk tween. Tires having-Smetailic band-supports in the rubber are also`objectionable because the resiliency of the tire islessened by the metallic supports and because the metallic bandsupports are destructive to tliepelastic body, when the tire is in use and oftenbecomeloose and cut or abrade the elast-ic material, thus lessening the durability ofthe tire.

The present invention designs to overcome these objections and to provide metallic snpvports for theretaining band or bands, which are securely held in proper position with respect to the elastic body, but do not extend through the elastic material or body, so the band-support need not be embedded in the elastic body or. extend therethrough.

`The invention also designs to provide improved .supports for the retaining-band, which do not affect the resiliency of the elastic body,` and, further, to provide a cushion tire embodying animproved construction. y

The in vention'consists iu the several novel features hereinafter set forth, and more par-V ticularly de fined by claims at the conclusion hereof. Y

A denotes a metallic rim-of usual construction and comprising a base a and flaring side tlanges rt', between 'which a channel is formed. An elastic strip or body B, usually formedof rubber or rubber compound, comprises a b e portion L and a tread portion 7;', adapted to t into the rim-channel` The base and sides f the elastic body maybe' lined with a strip o canvasC, if desired. Each side of body B ig formed with a flange or seat b for a retaining band D, which extendslongitudinally around .body B to secure the elastic body to the rim. VY'A'series of supports E, formed of metal,

secure the retaining-bands in position at the.

sides of the elastic body and effectively preventcuttmg or Wear of said body by the retaining-bands. Each .support E comprises a transverse portion or bar e and sides or legs ing shown in position adjacent the Fig. 5 is a perspective showing \are'longitudinally positioned or spaced along said body. Supports E are usually formed of thin .slightly resilient or flexible stri-ps, so

the sist-terminals e2 can be sprung or forced\ into position about the elastic body. The upper ends of seat-terminals @2 are preferably bent away from the elastic body, as at e, so

the sides of the tread portion of the body will not be cut or abraded as a result of compres'- j sion and lateral play ofthe body, whichoc cur when the tire is in use.` Said ends t" arel arranged Within the outer edges of the rim, 95,

so tbe-y will ground. Y

The longitudinal retaining-bands when in position to secure the tire engage the profeeting flanges or seats If of the elastic body and\ Anot, come in contact with the loo I also rest in the seats of supports E. There.\ fore the tightly-drawn bands will f irmly se` cure theA elastic body or strip in the rim, but

without danger ofcutting or wearing the elastic strip. The sides e' of supports E vare firmly clamped between the rimsides and the base portion of the elastic body, and the connecting-strips e pfsaid supports are firmly clamped between the .bases of the elastic'body and rim. The retaining-bands are located at the sides of the elastic body and adjacent therim, so the bands areconined against out- VWardmovement by the ri- The'seats e of l 'supports E, within which thfej retaining-bands rest, prevent inward movement ofthe bands and cutting and ywear of the elastic body by the bands, such would result from comi pression andlaterall strains to which the tire is subjected when in use.

Seats e: are slightly depressed to hold the bands so they cannotl slip betweenthe 'elastic body and rim side, which often occurs when the ends of cross-V supports heretofore used become worn or broken.- Y 1 In Figs. 4 and 5 there is showna modified .form of the inventionin which the band-supports are formed of a long strip of thin ilexible vmetal cut and bent to form a longitudinallyextending base-strip es, adapted to A lie between the base of bodyhB and the rim-base and to form band-supports E', which are integrally formed therewith, Aand sustain. the bands in the same manner as the-'supports E hereinbefore described. In this form the con; meeting-strip es spaces the supports along the elastic body and permits the supports to 'be bent for rims of different diameters.

*In Fig. 6 there is shown one Way of applying the supports to a tirewhich is formed o an elastic body B' and a base IBi of superposed layers of textile fabric. A 'In this form of .the invention the bars e of the band-supports are placed between the layers of the fabric base, which-are vulcanized together between the supporting-strips.

Manifest'ly the invention provides support- `ing means for a retaining-band, which can be i applied to the tire independently of the elastic body-zi. e., Without embedding the support in o1' extending the support through the elastic body. The supports shown are clasped around the elasticbody and can be readily appliedafter the. elastic body has been formed.

Theseats o the band-supports securev the bands against inward tendency likely to cut or abrade the elastic body, and, moreover, the bands are etectively secured against lateral movement in either direction. It will also be observed that th-e supportsv extend between the elastic body and rim, between ivhich they are firmly clamped and held. Furthermore, by extending the supports between the base of the rim and the elastic'body the supports are better secured against longitudinal and transverse strains. I., y
